The Constitution of 1845 established the state office, which replaced a similar office under the Republic of Texas.
The Constitution of 1876 officially renamed the position and established it as the office of secretary of state. The office's major duties include attesting the governor's signature; affixing the state seal to proclamations, commissions, and other documents; and acting as chief election officer. Some early secretaries of state include Allison Mayfield, T.H. Bowman, J.D. Templeton, and A.J. Searcy.
